对某酒店中央空调系统和生活用热水系统进行改造,将带热回收的螺杆式冷水机组代替单冷螺杆式冷水机组;回收冷凝热以满足生活热水的需要;最后将系统改造前后能耗进行分析,结果表明改造后主机效率有较大提高,综合能耗明显降低,比改造前能耗降低21.6%。
The central air-conditioning system of a hotel and domestic hot water system transformation, with the heat recovery of screw chillers instead of single-screw screw chillers; recovery of condensing heat to meet the needs of domestic hot water; and finally the system before and after the transformation of energy consumption The results show that the efficiency of main engine is greatly improved, the comprehensive energy consumption is obviously reduced, and the energy consumption is reduced by 21.6% compared with that before the transformation.
